1. Quick Reference Guide

1.) Start up the wireless room temperature sensor (transmitter) and plug the

wireless heating control (receiver) into the electrical socket

2.) Briefly press the register button on the wireless heating control 씮 The

light flashes red

3.) Switch the wireless room temperature sensor to registration mode until

the light on the wireless heating control flashes green.

4.) Mount the wireless room temperature sensor at suitable location,

set the desired temperature. The control is now active.

2. Use

This wireless heating control (receiver) was specially designed for mobile

heaters and is used with one or more wireless room temperature sensors

(transmitters). For uses which were not anticipated by the manufacturer, follow

the applicable safety regulations. With regard to suitability for unanticipated

uses, see Item 12, Warranty.

3. General Function / Installation / Maintenance

The HTFRA-010.101 receives the target and actual values from the registered

wire-less room temperature sensors (transmitters) and switches the heating on

when the temperature drops below the target value. Up to ten wireless room

temperature sensors of various types can be registered with the wireless hea-

ting control (receiver) (see Item 4.2). In the event of a power failure or when

starting up the device again after being switch off, the registered wireless room

temperature sensors are still saved. After the power has been restored, the con-

trol is active again within five minutes. The wireless room temperature sensor

with a clock has an on/off button which can be used to shut down the control.

If you use a wireless heating control without a wireless room temperature sen-

sor with a clock, you can completely deactivate the heating control for this room

by removing the wireless heating control from the electrical socket. The range of

the wireless connection is largely dependent upon the room conditions and the

battery charge level of the wireless room temperature sensors. Reinforced walls

and ceilings and metal casings reduce the effective communications range. This

device does not require maintenance.

4. Initial Operation

After being plugged into the electrical socket, the wireless heating control

(receiver) is immediately ready for use and the wireless room temperature

sensors (transmitters) belonging to it can be registered (Item 4.1). When relo-

cating mobile heaters, ensure that the wattage is correct, that the electrical

socket has sufficient fuse protection, and that the plug is firmly seated in the

electrical socket. After assigning the wireless room temperature sensors to the

wireless heating control, ensure that heating is functioning using the actual

transmission path. To do so, set the target value of the wireless room tempera-

ture sensor to the maximum value. Heating must activate within three minutes.

If you perform installation when the ambient temperature is close to the maxi-

mum value of approximately 30°C, the wireless room temperature sensor(s)

must be carefully sprayed with coolant. In doing so, be sure to apply a moderate

amount of coolant spray and only spray the internal NTC temperature sensor

area near the lower ventilation slot.

Caution: Do not spray coolant on any displays and make sure they are covered

appropriately.

4.1

Registration function (establishing the

wireless connection)

The registration function is used to assign a wireless room temperature sensor

(transmitter) to the corresponding wireless heating control (receiver).

Before registration:

A wireless room temperature sensor can be registered with a wireless heating

control in the following three scenarios:

1.) A wireless room temperature sensor has not yet been registered with the

wireless heating control. In this case, the light on the wireless heating control is

continuously red.

2.) One or more wireless room temperature sensors were registered with the

wireless heating control within the past hour. In this case, the light on the wire-

less heating control is green, indicating a working wireless connection to the

sensors.

3.) One or more wireless room temperature sensors were registered with the

wireless heating control more than one hour ago. In this case, the light on the

wireless heating control is off, indicating a working wireless connection to the

sensors.

Registration procedure:

Note: To activate the registration mode on the wireless room temperature

sensors, follow their operating/installation instructions. There is usually a

with a display may also have a button combination with indication on the

display.

1.) Briefly press the register button on the wireless heating control. 씮 The

light on the wireless heating control flashes red for a maximum of 30 seconds.

If no wireless room temperature sensor is registered during this time, the light

stops flashing and returns to its initial state.

2.) Activate the registration procedure on the wireless room temperature sensor.

씮 The light on the wireless heating control switches from flashing red to

green, and the wireless connection is established.

Light / Register Button

4.2 Registrable device types (function types)

Function type 100 can have up to nine transmitters registered in the following configurations:

Function Type Symbol Transmitter Description Maximum Registrable Number

001 Wireless room temperature sensor 7*

002 Wireless room temperature sensor with a target value regulator 1**

003

Wireless room temperature sensor with a target value

1**

regulator and comfort/energy-saving operation mode switch

004 Radio ECO contact 1* / ***

010 Wireless room temperature sensor with a clock 1***

* A set point setter- or clock-equipped transmitter needs to be assigned in addition to the transmitters.

** No more than one set point setter-equipped transmitter can be assigned. The assigning of a second set-point setter equipped transmitter deletes the data stored for the

first one. Only the data of the transmitter that has been assigned last remain valid.

*** No more than one transmitter can be assigned. The assigning of a second transmitter deletes the data stored for the first one. Only the data of the transmitter that has

been assigned last remain valid.

4.4 Wireless connection function and

assignment check

You can use this function to check whether wireless room temperature sensors

(transmitters) are correctly assigned to various wireless heating controls (recei-

vers). This makes it easy to find mistakes later on.

씮 Start the registration procedure on the wireless room temperature sensor.

씮 During this time, the light on the wireless room temperature sensor flashes

red. If the light on the wireless heating control starts to flash green, the sensor

is registered with it and the wireless connection is established. Caution: For

wireless room temperature sensors with a register button, only press the button

briefly. If you press the register button on the wireless room temperature sen-

sor longer than ten seconds, the device switches to deregistration mode (see

Item 7.1).

4.3 Installation mode indication

The temporary installation mode indication on the wireless heating control

helps you to more quickly check the wireless connection under the actual con-

ditions of use during installation. Installation mode begins when a wireless

room temperature sensor has been successfully registered and lasts approxi-

mately one hour. During this process, installation mode is indicated by a conti-

nuous green light. When you register more than one wireless room temperature

sensor, the time starts over after the last registration procedure. To reduce in-

stallation time, any loss of connection during this time will be indicated after

two minutes. For other displays on the wireless heating control, see Item 5,

Indicator Lights. After placing the wireless room temperature sensor in the

room you want to regulate, you should again check for the continuous green

light on the wireless heating control to ensure that the wireless connection is

working. If the wireless connection has been interrupted, the light will turn red

after two minutes. One hour after registration, the green light goes out, indica-

ting normal operation.

5. Indicator Lights on the Wireless Heating

Control

Light off: Normal operation mode, provided that:

the wireless heating control is powered (see Item 4.1).

Continuous green: A wireless room temperature sensor was registered

less than one hour ago (see Item 4.1).

Flashing green: Manual connection test with a wireless room temperature

sensor. 씮 Wireless connection is working (see Item 4.4).

Continuous red: Loss of connection to at least one wireless room

temperature sensor, no sensor has been registered, or all

sensors were deleted (see Item 8).

Flashing red: Registration mode (see Item 4.1)

6. Measuring the Temperature from Multiple

Wireless Room Temperature Sensors

(Average-Value Control)

If, in addition to the wireless room temperature sensor with a target value regu-

lator or clock (function types 002, 003 and 010), you register additional wire-

less room temperature sensors without target value regulators (function type

001), the wireless heating control averages all received actual temperature

values. Caution: Since the temperature control results from the comparison of

target and actual values, you must register a wireless room temperature sensor

with a target value regulator or a clock. If you only register wireless room tem-

perature sensors without target value regulators, the control will not be active,

due to the missing target value. Average-value control should be used in large

rooms and rooms with many corners, where uneven heating can be expected.

6.1 Master-slave control (automatic operation

for multiple rooms via central wireless

room temperature sensor with a clock)

6.1.1 Explanation of terms

Master (main control or pilot control) – is a higher-level control with a higher

priority than the slave control, which influences the temperature control of the

room in which it is installed and is also responsible for energy-saving times and

special functions in all rooms where it has been registered.

Slave (follow-up control or satellite control) – is a lower-level control with

less priority than the master control, which only influences the temperature

control of the room in which it is installed.

Energy-saving times – are time periods when heating is adjusted to a lower

room temperature or cooling is adjusted to a higher room temperature in order

to save energy. Energy-saving times are usually during the regular absence of

persons or during rest periods and can therefore be entered as a clock program

in the master.

ECO temperature – ECO (also ECON) comes from the word “economy” and

refers to saving. With regard to room temperature control, energy is saved

during the absence of persons or during rest periods by adjusting the tempera-

ture to a value which allows the consumers to be switched on less often instead

of to the comfort temperature.

Special functions – are functions that are activated by the master device. These

functions include holiday function, party function, on/off function, self-learning

function, and valve and pump protection. These functions are described in the

operating/installation instructions of the master.

Wireless heating control (also called “receiver” colloquially)

– is a heating

control that receives target and actual temperature values and other special

functions wirelessly and adjusts the heating for the room accordingly.

Wireless room temperature sensor (also called “transmitter” colloquially)

–

is a temperature sensor that measures the room temperature and transmits this

value to the wireless heating control wirelessly. Wireless room temperature sen-

sors are usually equipped with target value regulators to set the desired tempe-

rature. An exception is a wireless room temperature sensor that is used for cal-

culating the average room temperature when the room heats unevenly. Wireless

room temperature sensors with clocks use a time-controlled energy-saving

function for individual-room temperature control and can be used as a master.

6.1.2 Installation of master-slave control

The master-slave control is an extension of an existing individual-room tempe-

rature control. For individual-room temperature control, a wireless room tempe-

rature sensor with a target value regulator (transmitter) is registered with each

wireless heating control (receiver) of a room. To establish a master-slave con-

trol, an additional wireless room temperature sensor with a clock is registered

with the wireless heating controls of the individual rooms. During installation,

you do not have to pay attention to the sequence in which the different wireless

room temperature sensors are registered, but note Item 4.2. No other wireless

room temperature sensor is installed in the room where the master is. For the

master-slave control, you should pay special attention to the range of the wire-

less connection, since installation requires greater transmission paths to be

bridged. Therefore, after installation you should check the wireless connection

over the entire transmission path (see Items 4.3 and 4.4).

Wireless room temperature sensor function type 003 has a switch that you can

use to switch between comfort and energy-saving operation modes. Within a

master-slave installation, the ECO function of the switch switches automatically

to “participation in master-slave operation”. In the comfort operation switch

setting, the room will not participate in master-slave operation, and the tempe-

rature is permanently set to the target value of the room sensor.

7. Deregistration of All Wireless Room Tempe-

rature Sensors from the Wireless Heating

Control (Deletion of Entire Reception Channel)

This function is required to delete non-functional transmitters from the memory

of the wireless heating control.

씮 Press and hold the register button on the wireless room temperature control

until the light turns continuous red after approximately 10 seconds. The

successful deletion of the entire reception channel is indicated by a continuous

red light for the deleted channel, and the control is deactivated. After the deletion

procedure, the wireless heating control is deactivated for approximately 30

seconds and will not react to any buttons pressed during this time.

7.1 Deregistration of individual wireless room

temperature sensors from the wireless

heating control

In order to deregister only one wireless room temperature sensor (transmitter)

from the wireless heating control, switch the wireless room temperature sensor

to deregistration mode and also briefly press the register button on the wireless

heating control. Follow the operating/installation instructions for the wireless

room temperature sensor. Always check whether a wireless room temperature

sensor has been successfully deregistered as described in Item 4.4. If no more

8. Failsafe Operation and Display When

Wireless Connection Is Interrupted

The failsafe function is triggered by battery failure that has gone unnoticed or if

the wireless connection has worsened due to other causes, such as the rearrange-

ment of metal furniture. If the wireless connection has been interrupted for one

hour, the wireless heating control activates the failsafe function and the light turns

red. If the wireless connection is interrupted, a fixed power-on time of 30% is

maintained to keep the room from cooling off and to prevent frost damage. If mul-

tiple wireless room temperature sensors are registered, failsafe operation is

always activated when the connection to a sensor is lost. The 30% power-on time

is segmented into three minutes on and seven minutes off. Caution: The failsafe

function is activated when a connection is lost, e.g. due to discharged batteries,

even in summer. To prevent the heating from being unintentionally turned on (and

thereby causing an undesired use of energy in seasonally used buildings or

rooms), we recommend disconnecting the heating from power when it is not

being used, such as during the summer. To do so, unplug the heating or wireless

heating control from the electrical socket.

6.1.3 Master-slave functions

For these functions, also follow the operating/installation instructions for the

master being used.

Energy-saving function – The energy-saving times entered in the master apply to

all rooms in which the master-slave control is installed. During comfort heating

times, the temperatures set on the individual slaves apply. During energy-saving

times, the ECO temperature of the master applies, but only if the master’s ECO

temperature is lower than the slave’s comfort temperature. The energy-saving

function is activated for all rooms with slaves when the master is set to the ECO

operation mode.

Holiday function – The holiday time entered in the master applies to all rooms

in which the master-slave control is installed. During holiday time, the holiday

temperature of the master applies, but only if the master’s holiday temperature

is lower than the slave’s comfort temperature.

Party function – The party time entered in the master applies to all rooms in

which the master-slave control is installed. Until the end of the party time, the

temperature in all rooms is adjusted according to the comfort temperature

values of the individual slaves.

On/off function – The on/off function on the master applies to all rooms in

which the master-slave control is installed. Caution: This function does not pro-

vide frost, valve or pump protection. If these functions are to be provided with-

out switching on the heating when undesired, set the operation mode on the

master to “ECO energy-saving operation” and set an appropriate desired ECO

temperature for the frost protection. You can also set the target temperature in

all rooms to the minimum.

Self-learning function – If the self-learning function in the adjustment menu of

the master is activated, it applies to all rooms in which the master-slave control

is installed. Here it is assumed that the times required to heat up the individual

rooms are not that different.

10. Dimensioned Drawing

sensors are registered, the light on the wireless heating control will be red after

the deregistration procedure. If additional sensors have been registered less

than an hour ago, the light on the wireless heating control will be green. If addi-

tional sensors were registered more than an hour ago, the light will go out.

Caution: If the wireless room temperature sensor is not deregistered success-

fully and is removed from the room to be regulated but is still within the trans-

mission range, this leads to an undefined incorrect control. If the wireless room

temperature sensor is not deregistered successfully and is removed from the

transmission range, this leads to a lost connection message and the failsafe

function is activated.
